The dynamics of slice requests is considered by [1]} in
the SAC problem. If not accepted, a request is queued for being potentially
served later. The case of impatient tenants, who may leave their queues
before being served, is taken into account. Nevertheless, neither
the dynamics of resource demands within each slice, nor the activation
time of a slice are accounted for. Moreover, infrastructure resources
of each type are fully aggregated. As opposed to [2]}
and to our work, none of the details about the structure of the slice
and of the infrastructure are taken into account in the resource model.
Consequently, the proposed mechanism does not allow to reserve nor
allocate resource to the slice in addition to admission control.
